Application filed October 13, 1900 Serial No. 228,339.

To alt whom it 71I.(I/ concern:

Be it known that I, Louis P. Ronnie, a citizen of the United States, residing at Adrian, in the county of Nobles and State of Minnesota, have invented a new and useful Watchcase-Pendant, of which the following is a specification.

This invention relates to Watchoase-pendants.

The object of the invention is in a ready, simple, thoroughly feasible and practical manner and Without necessitating any extended change in the structural arrangement of stem-Winding-Watoh pendants in use to render the same dust-proof and to effect the assemblage of the stem and its accessories with the pendant in such manner posiively to reclude any loosening in use.

With t e above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a watchcase-nendant as will be hereinafter fully described and claimed.

p in the accompanying drawings, iorining a part of this specification, and in which like characters of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation,'it be ing understood that the elements therein exhibited maybe varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof.

in the drawings, Figure 1 is a view in el vation, partly in section, exhibiting 'tiLQ- parts of the pendant as they appear when in normal position. Fig. is a perspective detail view'showing the various parts of the stem and dust-cap separated. 3 is a fragmentary detail. view of a portion oi the pendant mechanism, showing the normal position of the parts, or that assumed when the watch lid is closed. Fig. i is asimilar view exhioiting the disposition of the parts when the crown is depressed for the purpose oi raising the lid and releasing case-spring. 5 is a similar view showing the position of the parts when setting the hands from the pendant. Fig. 6 is an enlarged sectional detail view of a portion of thepcudant, showing the irnprovcmonts applied thereto.

Referring to the drawings, 3 designates a portion of a \vatchcase center, which may he oi the usual or any preferred construction, and 2 the pendant. 'lhc latter, except in certain particulars hereinafter to be pointed out, may he of the kind in ordinary use or any other preferred design, and as this will be obvious illustrationv of additional iorins is deemed unnecessary. It may he stated at this point that the improvements of the present invention are adapted for watchcases of any size, for either hunting-case or open-lace cases, or for lever or pendant set movements. he present invention. resides more par-- ticularly in the means for combining the stem with the pendant and in a novel construction of dust-cap. The stem 3 is provided with the usual square terminal i to en.- gage the Winding and setting Wheels of a Watch-movement, with a shoulder 5 to on gage the case-spring 6 to release the same from engagement, a circula shoulder 7, a threaded terminal 8, and with a reduced intermediate portion ,9. Combined With the stem is a spring-sleeve consisting of two parts 10 anr 11, connected in the usual manner to permit the part if) to have rotary movement independently of the part 11. The part 10 is siitted longitudinally of its length to present a liuality of resilient fingers, the terminals oi which are inturned to form a flange 12 to interlock with the shoulder 7 when the improvement is employed on a pendant-set )VtttfilldllQVQ- merit, as shown in 5. Whenthe improve lent-s used in connection with a lover-set watch-movement, the flange 12 will normally bear against the nope-r face i3 oi the shoulder 7, clearly shown in Fix 3. The reduced intermediate portion 9 of tne stem. is furnished "for the purpose of reducing friction between the flange 12 and the stem when the latter is moved forward and back in the act or: relensing the case-spring. The part ll of the spring-sleeve pro vidcd with an enlarged externally-threaded shoulder 14-, which is longitudinally slitted, as at if), in order to render the threaded sec tions thus formed resilient, thus tooause them firmly to bite into threads formed internally oi the upper portion of the as clearly shown in i i, thislattei' portion of thepcmlant being also externally threaded to he engaged by the internal threads of This dust-cap is provided W1 through. which projects the upper portion of the stem, and the threaded terminal oi the latter is engaged by the crovni l8, which is provided with the usual central orilice for the purpose. 'il'ie dustdustcan iii:

a central aperture ill,

with the lid or cov r, with cop rests upon a. shoulder 19, formed on then placed over the projecting end of the pendant, and thus provides it dust-tight oint at this point. to prevent entrance of dust between the stern and the cap, there is e washer 20 provided, preferably of leather, WhlOlfl ISdISpOfSGd upon upper end of the pendant and 1S clamped in piece by the esp, which, as before stated, e1 'es the exte threads of the pendent. 11l6 it is ellv preferred to enin the lesther W2 1 A 1 L it is to be understood the inven ferred, be omitted between the dust-oe upon to form a dustproo'f joint. is provided with socket 21, i the dust-esp and operates in ner to effect Winding of the i the releasing of the ease-spring.

By reducing the upper portioi'r of the pendant to receive the dust oep the size of the former is not increased, as 'in practice the dust-cap will be just as thick as the WW0 01" metal l8II'lOV6d to form the rcduee tion, so that a pendent provided with this improvement will have the appearance oi. one of ordinary construction.

In assembling the device with n Wotel is the. spring-sleeve, the parts Whi e ii. been previously combined, is pped oi stennsnd the stern and sleeve are the sorted Within the bore of the pendent, and b" the employment of a. suitable implement Which will engage the slits 15 or" the pert 11 of the sleeve the letter Will be turned to its place end edjusted to cause the stem to seeupy the proper position. washer is stern, and the dust-cap is then screwed in sition. After this the crown is combined with the stern in the usual manner, and the device is then ready for use.

it will be seen from the foregoing description that olthough the improvements of this invention are simple in character they Will found thoroughly efficient in use for the 1 .roose designed and maybe readily adap ted pendants of the ordinary construction 4 .iout objectionable expense or any marked v 3 in their structural zirrgrngeinent. iiwving; thus described the invention, what ed is combination with. e watch-pendant its upper portion reduced and internd externally threaded, of a sleeve 11 port to engage the internal threads, un 'PYOjGCtiilg through the sleeve, LL Washer disposed upon the free end '01 the 11116, n dust-cop of the same trm'isversc es the pendent and engaging the ternul threads thereof to clmnp the washer z'minst the pendent and around the stern, dustpsp being provided with an orifice tnrough which the stern projeets and e crown ns cred with the stern and partly housing in testimony that I claim the foregoing as rev own i have hereto otlixed my signature in the presence of two witnesses.
